سونوگرافی در آب

Sonohysterography or ultrasound in water, also called saline infusion sonography (SIS) or sonohysterogram, is a method of examining the inside of the uterus. This is a safe test that uses sound waves to create images. It does not use radiation.

method of doing

During sonohysterography or ultrasound in water, you will be awake and lying with your knees bent. An ultrasound transducer is placed in the vagina. which is covered with a disposable sheath and covered with a special gel.

The doctor then inserts a thin, flexible tube (catheter) into your cervix. A salty liquid called saline is sent into your uterus through a catheter. At the same time, the transducer sends sound waves through the gel to your body. The echoes of these sound waves create a real-time image of the inside of your uterus that shows the structure of your uterus. Saline fluid helps the ultrasound to form an image with sharper details.

In addition to providing important information about your uterus and ovaries, ultrasound in water can detect if your fallopian tubes are open, determine if you have ovarian cysts, and measure your antral follicle count.

Doctors use sonohysterography, or ultrasound in water, to help diagnose a number of medical conditions, including:

  • Uterine fibroids
  • uterine polyp
  • A scar inside the uterus
  • Abnormal shape of the uterus
  • uterine cancer

Hysterosalpingography: This is a type of imaging that uses radiation.
Hysteroscopy: This surgical procedure is performed under anesthesia.
MRI: This imaging test is performed with large magnets and a computer. MRI may not provide a clear image of the inside of the uterus.

What are the risks of hysterography?

Sonohysterography or ultrasound in water is a safe procedure with few risks. Some women feel discomfort during the procedure and may experience cramps during and after the procedure. In very rare cases, there is a small risk of pelvic infection. Your doctor will take steps to prevent this.

Women with active pelvic inflammatory disease (PID) should not undergo this procedure. The doctor may recommend a pregnancy test before the procedure. This is to avoid any potential danger to the growing baby. Pregnant women are not allowed to undergo saline sonohysterography.

Important points:

  • It is better to do this procedure one week after the end of menstruation. This helps the test to be more accurate. It also reduces the risk of infection.
  • You can eat and drink normally on the day of surgery. You will most likely be able to take all your medications as usual.
  • Your doctor may recommend taking an over-the-counter pain reliever ahead of time to help prevent discomfort.
  • You may be told to take antibiotics before the test to prevent infection.
  • You may want to wear an absorbent pad in your underwear on the day of the operation. This is because after the operation, saline fluid is removed from the uterus.
  • Your doctor may give you more instructions on how to prepare.
  • Before starting, he should empty his bladder. Then you undress from the waist down and lie on the exam table. You are awake and alert to perform this test. You may experience muscle cramps during and after the procedure.
